CallConvBug.cpp: In function `int main()':
CallConvBug.cpp:20: no matching function for call to `avsquirt::avsquirt
(void (
&)())'
CallConvBug.cpp:10: candidates are: avsquirt::avsquirt(void (*)())

The problem is that the compiler mixes up the calling conventions for
function types with the same prototype. Attached is the zipped preprocessor
output, as requested.
